Example Embodiment
[0048] Example 1
[0049] The construction method using self-suspending clean water fracturing proppant includes the following steps:
[0050] (1) Use a high-pressure pump truck to pump natural water into the downhole reservoir at a displacement of 2 cubic meters per minute for fracturing to form initial fractures;
[0051] (2) Continuously add clean water as the sand-carrying fluid in the sand mixer, and at the same time add the self-suspending clean water fracturing proppant at a displacement of 2.2 cubic per minute to make a sand-carrying fracturing fluid, and the sand mixing time is 10s; The volume ratio of the clean water fracturing proppant to the sand-water volume of the sand-carrying liquid is 40%, and the relationship between the sand mixing speed Y and the sand-water volume ratio X is controlled at Y = 118.35X 0.1918 ;
[0052] (3) After the initial fractures are formed, a high-pressure pump truck is used to continuously pump the sand-carrying fracturing fluid into the initial

[0062] The construction method using self-suspending clean water fracturing proppant includes the following steps:
[0063] (1) Use a high-pressure pump truck to pump natural water into the downhole reservoir at a displacement of 2.5 cubic meters per minute for fracturing to form initial fractures;
[0064] (2) Continuously add clean water as the sand-carrying fluid in the sand mixer, and at the same time add self-suspending clean-water fracturing proppant at a displacement of 2.6 cubic per minute to make a sand-carrying fracturing fluid with a mixing time of 12s; self-suspension The volume ratio of the clean water fracturing proppant to the sand-water volume of the sand-carrying fluid is 45%, and the relationship between the sand mixing speed Y and the sand-water volume ratio X is controlled at Y = 118.35X 0.1918 ;
[0065] (3) After the initial fractures are formed, a high-pressure pump truck is used to continuously pump the sand-carrying fracturing fluid into the in

[0075] The construction method using self-suspending clean water fracturing proppant includes the following steps:
[0076] (1) Use a high-pressure pump truck to pump natural water into the downhole reservoir with a displacement of 1.5 cubic meters per minute for fracturing to form initial fractures;
[0077] (2) Continuously add river water as a sand-carrying fluid in the sand mixer, and at the same time add a self-suspending clean water fracturing proppant at a displacement of 3 cubic meters per minute to make a sand-carrying fracturing fluid with a sand mixing time of 15s; self-suspension The volume ratio of the clean water fracturing proppant to the sand-water volume of the sand-carrying fluid is 50%, and the relationship between the sand mixing speed Y and the sand-water volume ratio X is controlled at Y = 118.35X 0.1918 ;
[0078] (3) After the initial fractures are formed, a high-pressure pump truck is used to continuously pump the sand-carrying fracturing fluid
